Before any numeral key is depressed the parts are in theposition shown in Fig. 3. When the' key is depressed, as the engagementof the stud 32 with the summit 21 of the bar 9 occurs, the latch bar 22is lifted and this raises the stud pin 52 which moves upwardly andelevates the latch arm 49. As the latch arm is raised its notch israised to permit the notch 38 of the arm 37 to slip under it. Thispermits the elbow lever 36 to swing on its pivot 35 under the influenceof a spring secured to the arm 40 for that purpose. Such movement causesthe tip 11 to impinge against the lever 43 and oscillates it on itspivot 42 moving the hook 46 out of the path of a projection on the rackand type plate 81, hereinafter referred to, permitting the latter torise until such projection contacts with the end of the bar 9, which hasbeen moved rearwardly by the depression of the key referred to.

The accumulating mechanism consists of the numeral wheels and theirconnections. The numeral wheels are arranged at the rear 1 of-the keysystem and in the upper part of the casing. Each wheel is provided witha disk 67 having peripheral recesses, a pinion 61, and a cam plate 62,each made integral therewith, or-secured thereto in any suitable manner.1t is centrally apertured and loosely mounted to revolve on a shaft 63secured to and projecting laterally from an arm 64 which 1n turn ismounted on a pivot 65 projecting laterally from a sup porting plate 66.Each arm 64 has a tail 53, and at its rear end, is provided with alaterally projecting catch 68 made by bending to one side a portion ofthe arm itself. A spring 69 exerts a constant inward iension on the arm.Each numeral wheel is arranged Ato display on its periphery the numbersxfrom 1 to 0 in regular order in the manner usual to the art, and it isobvious that there one numeral wheel forv each denominational series ofkeys.

The supporting plates 66 are arranged 1n Ytransierse series across themachine, each plate having a right angled aperture adapted to receive abar 71 common to all of the plates and which holds them together andcompels them to move in unison. The plates 66 are spaced apart by meansof su lementary hars 72 secured to the bars 1 y screws 73. Each plate isapertured to receive a shaft 75 mounted transversely across the machineand terminating in the plates 5 and G. The several plates 66 constittein etlect a multiple frame supporting the numeral wheel system There aretwo other plates 70, one mounted al each side of this multiple frame andwhich are each provided with a square aperture 1o receive the bar T1 anda round aperture to receive the shaft T5. These plates are provided withprojecting pins 711, so that when these pins are moved the numeral wheelsystem is moved as an entirety and oscillates on the shaft 75. Therotation of the numeral wheels is secured by the engagement ot' theirpinions 61 with Inova-ble racks 80 provided for that purpose, and theextent of the movement of which in turn is governed by the keys whichhave been depressed. VThe racks 80 are'cut in the upper front edges ofver-,tical rack and type plates 81, each provided With a Wing 82 whichis adapted to carry the types (see Figs. 17, 21 and 23). These wingsextend rearwardly and are arN ranged to converge toward each other sothat at the printing zone the spaces between them will correspond tothat which usually obtains between successive figures of the font towhich the types belong. Vertical rods 83 are arranged to serve as guidesand supports for the plates 81, each rod resting in a recess formed in atransverse rib 81 at the base of the machine and at its upper endengagingr with the transverse plate 3U. Each plate 81 is provided withtwo guides 85 serving to cretain the plate in engagement with its rod.The rods 83 are hollow and each contain a spring 85, the lower end ofwhich is secured to a pin 88 passingthrough the guide 86 and plate 81and the upper end of which is secured in a slit 89 by a pin 90. Avertical slot 58 in the rod permits the movement of the pin 88. Eachplate 81 is provided at the lower part of its front edge with aprojection 91. and at the lower part of its rear edge with anotherprojection 92, the latter being adapted to engage with the restoring-bar 103 hereinafter described. The spring 86 normally tends lo raisethe plate 81 against the force of gravity. The racks 80 consist of teethot proper size and shape to engage the pinions 61 of the nu- -meralwheels 60.

95 is the main shaft of the machine mounted in suitable bearings in thebase 2 and adapted to be escillated in any suitable nian ner, butpreferably' by a handle 96 terminat ingin a gripping member 97 hemovement of the mechanism thus far described is accomplished from themain shaft in a manner fully described in -my prior application beforereferred to. Suitable aprings 122 secured to a rod 123 support from thebase of the machineand suitable connections 124 to the main shaft fromsuch springs serve to retract the parts to their initial positions afteractuation.

The adding, carrying', totaliziug and resetting operations of theaccumulating mechanisin being fully described in my prior application,and forming no part of this invention, will not be specificallydescribed herein.

The printing or recording mechanism will now be described.

Each wing 82 of the rack and type plates 81 serves as a type carrier.Each wing is bent inwardly at 180 and downwardly at 181 see Figs. 24 to28) and is provided with a removable partition 183 forming a housing forthe type. The internal member 180 is .provided with a series of tenround open- -ings 184 to permit of thevpassavepf the type, and thepartition 183 is provided with a similar series of ten oblong openings185 for the same purpose, the two series of openings registering witheach other horizontally.

The types 188 each comprise 'a round body 189 which is rovided withgrooves 190, a attened shan191 anda head` 192, the latter carrying thefi ure to be printed, (see Fig. 19.) A coile spring 193, one end ofwhich enga es in the groove 190, and the other end o which impingesagainst the inner side'of the member 180 and surrounds the type body,serves to retract the latter to position after actuation. The openings185 are made with substantially straight vertical sides and the shanks191 are flattened to correspond therewith in order to prevent the typefrom turning.

Type actuators 200 are arranged in the -front of the types, one for eachdenominational series. They each comprise a body 201 loosely mounted ona common shaft 202 and are s aced apart by suitable collars 203. Eachdiy is provided with a recess 204, a catch 05, a. striker 206 and an arm207 extendi toward the body of the next lower o`r`dervsee Fig. 7).

anged in the rear of and below the` type actuators are a series oftriggers 210 loosely mounted on. a transverse shaft 211 and spaced'apart by collars. Each trigger is provided with a spring 212 the otherend of which is secured to a cross rod 199 mounted between brackets 213.Each trigger has an upwardly extending arm 214 terminating in -a roller215l adapted, t9 engage withv the under surfaceof the corr nding rackand type plate 81, a downward y extending arm 216 terminating in a hook217 adapted to engage with the catch 205 on the type actuator 200,' andla projection 218 adaptedy t0 strike against a #ross rod 219 suitablymounted between two supplementary plates 220 and 221 mounted cn andsupported from the vshafts 101 and 226. The shaft 211 is mounted betweenthe two arms 102. By this' construction the triggers 210 can cach turnon the shaft 211 but the entire series of: triggers and the shaft 211are ada ted to oscillate on the shaft-101 as a who Arranged in front ofand below the parte justdescribed are energizing elbow` levers 225 eachloosely mounted on a cross shaft 226 supported in brackets 227 from thebase of the machine andn spaced apart by suitable collars 228. The upperarm 229 of each lever 225 Iis provided with Aa roller 230 adapt-Supposing an item to have been enumerated by the depression ofappropriate keys and the stop bars 9 to have been positioned thereby,the main shaft 95 is then oscillated by means of the handle 96 and therestoring bar 103 is lifted in the manner previousl;

described. This allows the appropriate rac and type plates 81 to riseunder the inuence of their respective springs and brings into positionat the point of print the types corresponding to the keys which havebeen depressed'. o All of the remaining plates 81, whose keys have notbeen depressed, rise a slight distance to bring their respective 0 typesto the point of print. Each plate; 81 is y similarly positioned at the 0point whenever the main shaft is actuated. In 'the meantime, as eachplate 81 rises Vits trigger 210 follows under the influence of its `spr1212, its roller 215 remaining in contact witthe loweredge of the plate81 until the hook 217 engages with the catch 205, when the trigger 210ceasesto rotate on its shaft 211, and the whole series of such triggersare rotated together on the shaft 101' which movement in turn causestheactuators 200 to 4swing on their shafts 202 and their recesses 204 tomove against the rollers 230 and thus swing the levers 225' against thetension of their springs 232 thereby stretching the latter. As therotation of each trigger 210 around the shaft 211 continues itsprojection 218 finally strikes the rod .219 and causes the trigger 210to swing on its shaft 211 and disengages the hook 217l from the catch205, whereupon the energizing elbow lever 225 smartly propels the hook206 of the actuator 200 against the shank 191 of the ty e immediately infront of it.

The ingin mechanism comprises an inkin lribbon w ich is carried uponspools and 'is rought into position in front of the line of print sothat the types when propelled forward hstrike. he ribbent.and movbitagainstt e recor in paper strip carrie y the platen, as hereignafterdescribed. The

ribbon has a. step by ste -movement from one spool to the other w `xclimovement is reversed automaticaly at the proper time and it has avertical movement whereby it is i elevated to the and depressed when notso uired.

y, Mpenv'enient places-near, v`- e; nar of the pointof print whenrequired,

machine and` on either side of the printing turned edges sect ion aretwo ribbon spool spindles 240 and 241 'vertically placed and-looselymounted in suitable bearings in the base 2, and upper plate 30.Eachnspindle is reduced in cross section at a convenient point to form aliange 242 on which rests a' ribbon spool 243 of usual form. A. tensionspring 244 is iuterposedbetween the top of each spool and the plate 30.Near the lower end of each spindle is secured a ratchet disk 245actuated by a pawl 246, which disk is keyed to the spindle and moveswith it. The pawl,

' when reciprocated, rotates the spindle inter# mittently agg-.minst thetension of the spring 244. Centrally placed and rigidly mounted on theshaft 101 is a downwardly projecting arm 248 at the extremity of' whichis loosely pivoted a reversing bar 249, provided at each end with a fork250 (see Figs. 32 and Loosely mounted on the shaft 101 on each side ofthe arm 248 are two crank arms 251, each prevented from lateraldisplacement by a pin 252 on the shaft engaging with a slot 253 on eacharm. Each crank arm is provided with an inwardly projecting foot 254having al downwardly projecting pin 255 adapted to engage with the fork250 of the bar 249. 0n each crank arm 251 is a lateral projecting smallshaft 257 on which is loosely mounted the pawl 246 between two inwardlycurved bearings 259 permitting a slight lateral movement of the pawl(see Figs. 32, 35 and 36). The pawl 246 is preferably made of a piece offlat metal twisted to bring its outer extremity into a horizon- `talposition and provided with a downwardly projecting tooth 258 adapted toengage with the teeth of the ratchet disk 245, the pawl 246 resting uponand being supported by this disk. A flat spring 256 is secured to thecrank arm 251 and is adapted to engage the side of the pawl 264 toholdthe same in engagement with the ratchet disk 245 (see Figs. 31, 35and 36h). Loosely mounted on one of the small shafts 257, in the machineshown in the drawings the one nearest the spindle 241 is a roller 250adapted to engage in notches 261 formed in the edge of an arm 262pivoted to a bracket 263 projecting` from the shaft 101 (See Fig. 37).

A spring 264 secured to the arm 262 and the brackets 263 holds theformer under a proper tension. The two pawls 264 are coupled t0- gethcrby a link 265.

v Means are provided for raising the ribbon 54 to bring it to the pointof print at thel proper time. On each side of the arm .248 and benvcenit and the cranks 251 are the two brackets 213, previously referredt0,'and

both rigidly secured to the shaft 101,. Pivoicd to and arranged betweenthese brackets is a lifting frame 268 provided at its upper edge. withtwo ways 269 with outwardly 56 adapted to embrace and guide the ribbon54 which is wound upon the spools 243. A downward extension 5T of theplate 30 serves as a lateral guide for the rack and type plates 81, andanother extension 5t) of the same plate serves as a guide for the upperend of the lifting fra-me 268.

lVhen the main shaft 05 is oscillatcd. a shaft 101 is also oscillated inthe manner previously described, and all ot' the parts secured to it ofcourse move with it. Referring to Fig. 31 it will be noted that one ofthe pawls 246 is in an engaging position with the disk 245 on thespindle 241 while the other pawl 246 is not. engaged with the disk onthe spindle 240 because its tooth 258 projects beyond the periphery of'that. disk. Therefore when the shaft 25 is oscillated and the shaft 101is also oseillated an intermittent movement is given to the disk 245 onthe spindle 241 through its pawl and the spool on that spindle isconsequently rotated to wind up the ribbon 54 thereon as shown in Fig.34. The spring 256 keeps the pawl in engagement with its disk. When theribbon has been fully wound on its spool, the

further rotation of the disk 245 by its pawl 246 is prevented, due tothe tensiion of the tightened ribbon. The disk 245 therefore holds thepawl at. the end of one of the forward strokes of the latter and insteadof the disk turning as theretofore, the pawl itself does not move at thenext backward oscillation of the shaft 101, but remains stationary Whilethe shaft itself turns. When this takes place, the crank 251 carryingthe small shaft 257 also remains stationary and the roller 260 on theend of this shaft is disengaged from one of the notches 261 and moves tothe other. This moves the crank 251 to its second position with respectto the shaft 101, and through the pin 255 engaging with the fork 250moves the reversing lever 249 on its pivot. e movement of the crank 251relative to the shaft 101 has also moved the spring 256 out of Contactwith its pawl 246 and no longer tends to hold the tooth of the pawl inengagement with its disk. The oscillation of the reversing lever 249has, however, moved the other pawl 246 engaging with the disk on thespindle 240 rearwardly to bring its tooth into engagement with said diskand its spring 256 to assistv and maintain said engagement. The furtheroscillation of the shaft therefore moves the disk on the spindle 240 andwinds up the ribbon on the spool on that spindle. The link 265 Vservesto maintain the pawls in vtheir relative positions and to keep one inalternate engagement with its disk.

The purpose of the lifter is to position the ribbon at the point ofprint each time an item is to be recorded and to remove it out of theway at other times. As above men tioned, the lifter is pivoted to thebrackets 213 and is raised and lowered by the shaft 101 at eachactuation of the main shaft. The parts are so arranged that the lifteris raised so as to bring the ribbon to the point of print at the eXtremeend of the forward stroke of the handle and after the actuators 200 havebeen moved forwardly to be in position to strike, so that the types arepropelled forward at the instant when the ribbon is in position. As therearward stroke of' the handle begins the lifter is lowered and theribbon is thereafter out. of the way until t ic main shaft is againactuated.

The paper carriage is mounted at the rear of the machine on the casing 3and is provided -with suitable actuating mechanism as fully described inmy prior application. The machine is also provided with a repeat key,means for absorbing the shock due to the return movement of theoperating handle, means for canceling an item enumerated on theN keyboard, a non-adding key, means for automatically counting the number ofitems accumulated. limiting the items to a predetermined number,interrupting such enumeration and automatically locking the numeralwheels when the last item has been enumerated, means for preventing theactuation of the operating handle when the total key is partiallydepressed and the numeral wheels out of engagement with the racks orpreventing the reversal of the handle after it has been partially movedin the proper direction, but these form no part of the present inventionand will not be particularly described herein.

The non-printing key comprises a key stem 410 having a finger piece 411and a notch 412 (see Fig. 14). It is hinged at its lower extremity toone end 0f an elbow 413, the other end of which is pivoted to a lever414 extending longitudinally of the machine and pivoted -to a crossshaft 415 which is adapted to oscillate a multiple detent 416 mountedbetween the two brackets 213. This y detent comprises a series of hooks417 which are so positionedas t9 engage pins 418'pro; jecting laterallyfrom the arms 216 of the triggers 210. It is obvious that when the key410 is depressed the hooks 417 are oscillated into the paths ofthe pins418 so as to intercept the triggers and detain them against movement(see Fig. 7). When they ane so prevented from moving, the type actuatorsare not moved or energized and no printing operation can take place. Thefunction of the printing mechanism is interrupted so long as the key 410remains` depressed. ll'hen the key 410 is released 1a spring 419 servesto retract it to its original position.

The non-numeral keys, namely the repeat key, the non-adding key, and thenon-printing key is each provided with a depending stem having a notchadapted to engage with the edge of the plate 14 for the purpose ofholding such keys in position after depression. It is not, however,

always desirable to hold them,

or any of them, depressed during more than one oscillation of the mainshaft and it sometimes happens than the operator will inadvertentlycause the engagement of the key stem by such notch moving under theplate 14 and thus use the key more than once when actually he desires touse it but oncen In order to avoid this accidental repeated use of sucha key,`means are. provided whereby the key cannot be accidentally lockedin a depressed position, but must be consciously moved by the operatorto 'be so locked and after being so locked must be positively andmanually released in order to be restored to its original position. Thedevice referred to is illustrated'in Fig. 47, the repeat key being usedfor that purpose. In this figure, the key stem is designated 410 and thefinger piece 411. There is pivoted` however, to the plate 5 a latch 235comprising a finger piece 236 and provided with ahook 237 adapted toengage a pin 238 projecting laterally from the key stem. There is also aretracting pin 239. The key stem is slotted at 234 to allow it to passthe pivot 233 of the latch. Vhen the key is depressed its stem 410 ismoved downward until it reaches the end of its stroke. If nothingfurther is done, as soon as the downward pressure, due to the finger ofthe operator, urally rise under the influence of its retracting spring.If it is to be retained in its depressed position the operator must movethe latch 235 so that its hook v237- will engage `with the pin 238. ythetension of the spring 239 and cannot ac- Y This movement is 'againstcidentally take place. 'Vhen it has -taken place the key will be helduntil it isl manually released. This is accomplished by tapping thefinger piece 411 lightly downward, because as soon asthe pin 238 ismoved below the plane of the beak of the hook 237, the spring Q39 willpull the hook out of the path ofthe pin 238 and the key will beretracted upwardly by its spring.

It has been explained how at eachactuw# tion of the main shaft therestoring bar 103 is lifted and the rack and type plates 81,001#-lresponding to the denominations in which no key has been depressed, areraised to bring their O types opposite the point of print because theparts are so proportioned that the beak of the hook 46 engages thepro'ection 91 to bring the O`type at the ot er end of the same plate 81to the properpoint."

It has not ben explained, however, how the zeros are automaticallyprinted. This will now be done.

Eachactuator 200 is provided with an arm 207, as above described, whichextends over toward the body of the actuator of next lower order, sothat when an actuator is moved its .arm engages with the actuator ofmuch is released, the key will nat.L

lower order (provided the latter has not been already engaged by its owntrigger 210) and bodily moves the latter to retract its energizer and bepropelled toward its type when the trigger -210 of the tirst namedactuator is released. Thus the rack and type. plate 8l in eachdenomination where no key is depressed is automatically moved to bringits 0" type to the point of print and its actuator is automaticallyenergized and propelled forward to print such type. In a similar mannerany other actuator of lower order, the rack and type plates of which hasbeen moved to the 0 printing point is actuated by the adjacentactuatorof higher order, whether such adjacent actuator lhas been brought to the0 point or4 to a point to print an integer.

It is to be noted that in the above described fnechanism, the parts arefree from complication in construction and mode of operation; theirmovement is direct and positive and usually in straight lines; they canlargely be made of standard material and without elaborate finishingprocesses;

their operation requires little power, thev key touch is light and thehandle action does not induce undue fatigue. There is accomplished inthis device everything accomplished in much more complicated machines,and in a more economical way, and the cost of its manufacture and use'isnecessarily less.

The carriage mechanism, the paper feed mechanism, the Slidable bracketsadapted to support the paper roll and the ribbon feed mechanism abovedescribed are, by a` requirement of the Patent Oiiice, removed from thisapplication and will be made the subject of other applications forLetters Patent. ot' the United States.
